` ANTON SCHWITTEB, OF BROOKLYN, NEW YORK.

Ross-ENGINE.

SPECIFICATION forming part of Letters Patent No. 307,340, dated October28, 1884.

Application filed May 15, 1894.

To a/ZZ whom it may concern,.-

Be it known that I, ANTON SCHWITTER, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York, haveinvented new and useful Improvements in Rosengines, of which thefollowing is a specification.' I

This invention relates to an improvement on the rose-engine described inLetters Patent N o. 297,454, granted to me April 22, 1884. The precisenature of my present improvement is pointed out in the followingspecification and claims, and illustrated in the accompanying drawings,in which'- Figure 1 represents aplan ortop view. Fig. 2 is a partiallongitudinal section in the plane y y, Fig. 1, on a larger scale thanthe previous figure. Fig. 3 is a transverse section iii the plane x x,Figs. 1 and 2. Fig. 4 is a face view of the slide-rest. Fig. 5 is asectional view of the pattern-spindle.

Similar letters indicate corresponding parts.

In the drawings, the letter A designates an arbor, which has itsbearings in standards B, and to which a revolving motion is imparted bya belt-pulley, C. On one end of this spindle is securedthe article to beornamented. In the example shown in the drawings this article consistsof a metallic disk, D, which may form the back plate of a watch-case.The

`standards B, which form the bearings of the arbor A, rise from abed-plate, E, and on this bed-plate is adjustably secured a secondarybed-plate, F, which carries the slide-rest G. This sliderest consistsofA two slides, a b, the slide a being fitted on a guide, c, which isfirmly secured to standards'd, rising from the secondary bed-plate F.'A. screw, e, serves to adjust the slide a on its guide c. The slide b isfitted in a guide-groove, f, extending transversely across the slide a,and it is pressed toward the end of the arbor A by a spring; or, ifdesired, this spring can be omitted, and the slide b can be pressedtoward the end of the arbor A by hand, as will be hereinafter more fullyexplained. In the head of the slideb is secured the tool or graver h,and also the tracer j, which graver and tracer extend vlongitudinallyfrom one face or side of the slide in the direction of the length of thearbor, in order to adapt the graver to operate on the outer face of anarticle carried directly on the (No model.)

end of the arbor, and also adapt the tracer to cooperate with apattern-die which is adjustable in a direction transversely to the axisof the arbor, as hereinafter explained.

H is the pattern-die, which is iitted on a spindle, I, and this spindlehas its bearings in boxes z', supported by a standard, J, which isadjustably secured to the main bed-plate E, (see Fig. 3,) and which issituated beneath the end of the arbor A, Figs. 1, 2, and 3, the centerline of the pattern being on a level with the tracer j. The frame .I andspindle I are arranged transversely, or at right angles to the axis ofthe arbor, which adapts one end ofthe arbor to be geared (as hereinafterset forth) to and revolved by a drive-wheel, o, adjacent to the end ofthe shaft which carries the article to be ornamented. The patternspindleI (see Fig. 5) is hollow throughout the largest portion of its length,and into its bore is fit-ted a slide, k, which connects by a pin, Z,with the pattern-die, said spindle being provided with a slot, Z2, inwhich the pinlmoves. The slide k is provided with an internalscrewthread to engage with a screw-rod, m, onthe outer end'of which issecured anger-button, u2,

On the screw-rod m is formed a collar, o2, which is confined between theend of the spindle I and a plate, p2, said plate being secured to aring, g2, which is firmly fastened on the end of the spindle byscrew-threads or; otherwise. By turning the screw-rod m, therefore, apositive motion can be imparted to the pattern-die in either direction,and said patterndie can be moved to the extent of the slot Z2 in thepattern-spindle.

On onevend of the spindle I is mounted a bevel-wheel, n, Figs. l and 3,which gears into a bevel-wheel, o, mounted on a shaft, p, which has itsbearing in a box adjustably secured to the standard J, and to whichmotion is transmitted from a shaft, q, which has its bearings instandards s, rising from or rmly secured to the main bed-plate E, andwhich is geared together with the arbor A by cog-wheels s, t, u, and o.(See Fig. 1.) These cog-wheels are so proportioned that thepattern-spindle I re volves at a greater velocity than the arbor A,which carries the work, (represented in this example by the disk D,) andin the example shown in the drawings an additional shaft, g, is shown,which is geared together with the ICO shaft q by cog-wheels w wo, sothat by transmitting motion to the pattern-spindle I from the shaft q",instead of from the shaft q, the relative velocity between the arbor Aand the pattern-spindle l is changed.- Of course,the same effect may beproduced by providing several sets of gear-wheels, so that the speedofthe pattern-spindle can be adjusted to avariety of work. The shaft q(or Q) is connected to the shaft p by two rods, ef Z1', which areconnected by a coupling, c', so that their combined length can beincreased or decreased, as may be requisite. The rod a is connected tothe shaft q by a universal joint, d', and the rod b is connectedtotheshaft p byauniversal joint, c', such being necessary because thetwo shafts p and q are not situated in line with each other, neither arethey at all limes inthe same plane, since the standard J must beadjusted on the main bed-plate F in accordance with the shape of thearticle to be ornainented. It will be seen from this description thatthe pattern-die is situated beneath the work and the tracerj directlybeneath the graver h. By this arrangement theadjustment of thepattern-die, the tracer, and the graver in relation to the work isfacilitated, particularly if the work has oblique surfaces, and bymounting the pattern-die on its spindle in such a manner that it isfirmly retained in its siate of rest the work produced is more correctthan it is if the pattern-die is liable to yield to the thrust of thetracer, which is the case if itis retained in position by a spring.

l do not claim in this application anythin shown and described in PatentNo. 297,45- heretofore mentioned.

I do not broadly claim agraver and a tracer arranged one above the otheron a slide-rest, combined with a pattern-die adjustable longitudinallyon va slotted shaft containing a screw-rod connected with thepattern-die, so-

that the latter is adjusted by rotating the screw-rod.

That I claim as new, and desire to secure by Letters Patent, is-

l. The combination of the revolving arbor for carrying at one end thearticle to be orna` mented, the spindle I, journaled in the frametransverse to the axis of the arbor under one end of the latter, thepattern-die H, adjustable longitudinally on the spindle, the slidearranged in advance of the spindle and movable toward and from the endof the arbor in the direction of the length of the latter, and thegraver h and tracer j, both carried by said slide and arrangedlongitudinally in the direction of thelength of the arbor, substantiallyas described.

2. The combination of the revolving arbor for carrying at one end thearticle to be ornament-ed, the slide-rest Gr, comprising the adj ustableslides c and b, the graver 7i, and tracer j, both carried bythe slide I)and arranged longitudinally in the direction of the length of the arbor,the frame J at one side of the sliderest transverse to the axis of thearbor, the transverse spindle l, journaled in the frame, and thepattern-dic H, adjustable on the spindle in a direction transverse tothe axis of the arbor, substantially as described.

3. rilhe combination ofthe arbor A, having a drive-wheel at or near oneend and a drivewheel, o, adjacent to its other end, the spindle l,journalcd transverse to the axis of the arbor beneath one end thereof,gearing connecting the spindle with the drive-wheel c on the spindle, apattern-die, H, adjustable on the spindle, a slide-rest, G, and thegraver 7L and tracer j, both projecting from one side of the slide-restin the direction ofthe length of the arbor, substantially as described.

Ll. The combination, with the arbor A, the slide-rest G, and the graverh and tracer j, both carried by the slide-rest, of the hollow slottedspindle I, the pattern-die H, movable thereon, the slide 7c in thespindle connected with the pattern-die, the'ring q2 on the end of thespindle, the plate p2, secured to the ring, the screw-rod engaging theslide and having a collar, o2, loosely confined between the plate andthe end ofthe spindle, and a finger-button, a?, on the outer end of thescrew-rod, substantially as described.

In testimony whereof l have hereunto set my hand and seal in thepresence of two subscribing witnesses.
